Java/C2/Hello-World-Program-in-Eclipse/English-timed

Time	Narration
00:01	Welcome to the spoken tutorial on HelloWorld in Java using Eclipse.
00:06	In this tutorial, we are going to learn how to write a simple Hello World program in Java using Eclipse.
00:13	For this tutorial, we are using Eclipse 3.7.0 and Ubuntu 11.10.
00:20	To follow this tutorial, you must have Eclipse installed on your system.
00:25	And you must know how to create, save and run a file in Eclipse.
00:30	If not, for relevant tutorials, please visit our website as shown.
00:36	Here is a line of java code that prints the message Hello World.
00:44	Now, let us try it on Eclipse.
00:46	Press Alt, F2 and in the dialog box, type eclipse and hit Enter.
00:56	Click OK at the workspace and here we have the 'Eclipse IDE'.
01:09	Now, let us add a new project.
01:12	Click File, New and select Project .
01:19	In the list of projects, select Java Project and click Next.
01:26	In the project name, type DemoProject (please note that there is no space between Demo and Project, D & P are in capital letters).
01:40	Click Finish at the bottom right corner of the wizards.
01:46	DemoProject has been created.
01:49	Now, let us add a new class to the project.
01:52	Right click on the Project, New, select Class.
01:59	In the class name, type DemoProgram and in the method stubs select one that says public static void main.
02:13	Click Finish at the bottom right corner of the wizard.
02:20	We can see that the DemoProject has the source directory and a file called DemoProgram.Java.
02:27	This is because every class in Java has to be in its own file. Hence the class 'DemoProgram' can exist only in the file Demoprogram.java.
02:40	We can see that there is very little space for the editor and the view looks cluttered. Let us minimize the other portlets and here we have the editor .
02:55	Notice that this line begins with two slashes which means this line is the comment and has nothing to do with our code.
03:05	Let us remove this line. Similarly every thing that is in between slash Astrix (/*) and Astrix slash (*/) is also a comment.
03:17	So, let us remove this comment also.
03:22	And here we have the bare bones of the code.
03:27	Now let us add the print statement, System.
03:35	Notice that eclipse gives a list of all the possible completions.
03:38	For now, we are going to type the command manually;
03:43	out.println. In brackets in quotes type: Hello World
03:56	In java, every statement has to end with a semicolon.
03:59	So, let us add a semicolon.
04:03	Here, these are complete HelloWorld program in Java.
04:06	Press Ctrl + S to save.
04:11	Right click Run as, Java Application to run the code.
04:19	As we can see on the output console, the message Hello World has been printed.
04:24	Now, let us change the "World" to "Java".
04:30	Save it with Ctrl + S and run it.
04:40	As we can see, the message that is printed now is Hello Java.
04:45	Now let us understand what each part of code does?
04:48	The first line indicates that the class name is 'DemoProgram' and it's a Public class.
04:55	The second line indicates that this is the main method. In other words the method from which execution starts with java.
05:04	As we know, this is a print statement.
05:07	And here is how we write a Hello World program in Java.
05:14	This brings us to the end of the tutorial.
05:17	In this tutorial, we have learnt how to write a Hello World program in java and also what each part of code does in java code.
05:27	As an assignment for this tutorial-
05:29	create a java class by the name Greet, it should bring "Program Successful" when executed.
